Cannot implement stubbing in JUnit Mockito

I am trying to write Junit test cases using Mockito. Whenever I am trying to use stubbing i.e use when and returnThen, I am getting a compile time error that the when is unidentified for that class. The following is my JUnit snippet

@Before
public void setUp() throws Exception {
registryIndexConfig = mock(RegistryIndexConfig.class);
when(registryIndexConfig.getIndexName()).thenReturn("Demogoblin");
}

I have imported the following classes, packages

import static org.junit.Assert.*;
import org.junit.After;
import org.junit.Before;
import org.junit.Before;
import org.junit.Test;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.testng.Assert;
import static org.mockito.Mockito.mock;
import org.junit.runner.RunWith;  
import org.mockito.runners.MockitoJUnitRunner; 
import static org.mockito.Mockito.stub;

Please can someone point what am I doing wrong here?

The methods mock, when, and many others are static methods in the Mockito class.

You must import them when using unqualified (with a static import):

import static org.mockito.Mockito.*;

Alternatively, you could import the Mockito class (like you did)

import org.mockito.Mockito;

and use the methods qualified:

@Before
public void setUp() throws Exception {
    registryIndexConfig = Mockito.mock(RegistryIndexConfig.class);
    Mockito.when(registryIndexConfig.getIndexName()).thenReturn("Demogoblin");
}

I prefer the static import way. It makes the test code look much cleaner.
